Insulation cuts
fossil-fuel dependence

Friday, April 11, 2008

Julie Kennedy, a technician with
A-A Exteriors, pours cellulose
insulation into a blower.

From the blower the insullation travels
through a hose that carries it into the
house and up into the attic.

A second technician sprays the insulation
over the less-effective fiberglass
insulation that was already in the attic.
